Stimulus

Essayist: Knowledge has been defined as a true belief formed by a reliable process. This definition has been criticized on the grounds that if someone had a reliable power of clairvoyance, we would not accept that person’s claim to know certain things on the basis of this power. I agree that we believe in clairvoyance, we would accept knowledge claims made on the basis of it.

The question

Which one of the following most accurately describes the essayist’s method of defending the definition

Answer choices

  1. Correct72% picked this

    asserting that the objection is based on a belief about the reliability of clairvoyance rather than on the nature

    Why this is right

    Did the author say, the reason for the objection is our belief about the reliability of clairvoyance, not about this definition of knowledge? Sure, the author said, I agree we would reject (object) to these claims, but we would do so because we really do not believe in clairvoyance as a reliable process. The author asserted that we object because of our beliefs about the reliability of clairvoyance. The final sentence is elaborating that this definition is not the problem, because were we to think that clairvoyance were a reliable process, it would satisfy the definition and we would happily accept calling it knowledge.

    Skill tested: Method · how this choice captures the argument's function is the move to repeat next time.

  2. Contradicted12% picked this

    asserting that the case of clairvoyance is one of knowledge even though we do not really believe in

    The author "agrees that we would reject a clairvoyant person's claim to know certain things based on this power". In other words, "You're right --- if a clairvoyant person claims to know XYZ via clairvoyance, we'd say you don't know XYZ." Our author thinks that clairvoyance is not a case of knowledge. He only thinks it would switch to being a case of knowledge if we were to switch into considering it a reliable process.

  3. Contradicted1% picked this

    arguing against the assumption that clairvoyance

    The author accepts (in a plural first person pronoun) that "we really do not believe in clairvoyance as a reliable process". He's not arguing against that assumption. He accepts the assumption that clairvoyance is unreliable.

  4. Out of Scope: personal choice1% picked this

    explaining that the definition of knowledge is a matter of

    The author never says the definition is a matter of personal choice. The author is defending this definition against an objection, saying that a supposed counterexample isn't really a counterexample. But he never explains that "how one defines knowledge is really up to them".

  5. Not a Case of "Reliable Process"14% picked this

    demonstrating that the case of clairvoyance is not a case of knowledge and does not fit

    So, so close. The author demonstrates that, the case of clairvoyance is not a case of reliable process and thus does not fit the definition of knowledge. The author does acknowledge that clairvoyance is not a case of knowledge, but that isn't part of defending the definition. The defense of the definition comes when the author says, "the reason clairvoyance isn't knowledge is because of reliable process, not because of bad definition."
